About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Low-Profile Square Manifolds

Aluminum

316 Stainless Steel

With outlets on the side instead of on top, these manifolds have a lower profile than rectangular manifolds and fit well in cramped spaces. Use them to distribute air, water, or hydraulic fluid to three locations from a single supply source. Manifolds have mounting holes, so you can mount from the top.

Anodized aluminum manifolds are the industry standard for the most common types of applications. They are lighter in weight than other metal manifolds and have good corrosion resistance. These manifolds are anodized for a black finish.

316 stainless steel manifolds have excellent corrosion resistance and can handle fuel, gasoline, coolant and other harsh substances.

Use a plug (sold separately) to close off any unused inlets and outlets.
